Impact of Valvular Prosthesis Type on Cardiovascular Outcomes in Patients on Chronic Dialysis

Abstract


There is conflicting evidence guiding valve prosthesis selection in patients with end-stage renal disease on dialysis. We sought to determine, after reviewing the relevant literature, the best valve substitute in patients on chronic dialysis. A total of 9 retrospective studies compared the outcomes of two valves, showing similar results and highlighting the safety of implanting bioprostheses in patients on chronic dialysis. Standards of valve selection have changed over time; it has long been believed that tissue valves undergo premature degeneration due to calcium metabolism derangements in patients with end-stage renal disease. Bleeding was the most common valve-related complication and represented a major drawback of mechanical valves. Two studies demonstrated a survival advantage in favour of mechanical prostheses. It can be concluded that surgeons should not hesitate to implant bioprostheses because singular valve decomposition would be uncommon in this patient population. Prosthesis selection should be based on the same criteria as those used for non-dialysis patients.
